About Dragon Boat Festival

The Dragon Boat Festival is a popular event in China, also it is a national holiday. It takes place on the fifth day of fifth month of the Chinese lunar calendar. This year it falls on June 3, Friday.

This celebration has been in existence for over 2000 years. What do people do to celebrate this Festival? We usually eat rice dumplings, drink realgar wine, and race dragon boats. Other activities includes hanging mugwort and calamus, taking long walks, writing spells and wearing perfumed medicine bags.

Dragon boat racing is the most popular part of this Festival. Boats are decorated to look like dragons. They can be up to 65 feet long. They can hold up to 22 people. Paddlers in the boat race train to paddle very quickly. They also train to paddle in sync with other team members. The team who wins the race believes they will receive good luck.


Happy Holiday, wish all Dolphin users good luck in 2022!

I have 4tb wd external hard disk purchased one month before. I accidentally click on format hard disk become 0 byte. I use some data recovery software but no data show. How to recover data?

This is one email from one single pc user asking for data recovery solutions to recover lost data from above WD 4TB external hard drive.

For this kind of format case, the recovery chance is on the windows os and users can confirm the failure detail by checking the hdd by winhex and find out if all sectors are 0000 or not.

Some format cases cause all 0000 and the data is gone; and some other format cases don’t affect the hex data much and the data is still there.

If the format case doesn’t have other failures, users just need to use data recovery software such as r-studio to scan lost files.

If the format case has bad sectors or firmware corruption, users need to use data recovery hardware tools such as DFL-SRP all-in-one data recovery equipment or DFL PCIE data recovery express to fix firmware issue or image the patient HDD or users need to use DFL-DDP to recover lost data by file types.

For WD SMR HDDs, they usually have firmware lock and SED V2 lock issue. To unlock the firmware area, users can use firmware unlock PCB. To fix the SED V2 issue, users can use the following methods:

1, Solder wires on original USB PCB;
